COMBUSTION DEVICE.

Application filed January 10, 1916.

To all whom it may concern:

Be it known that I, Onvrnnn G. HALLIBUR- TON, a citizen of the United States, and resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Combustion Devices, of which the following is a specification.

My invention relates to combustion devices, and, in its more specific adaptation, to such as may be employed in the fuel boxes of ordinary stoves and ranges whereby the ordinary coal or wood fuel for the fire box is replaced by liquid fuel yielding a flame of burning gas.

In general the objects of the present 1mprovements are to increase the efficiency of such devices and to render their installation, removal, replacement of parts, the cleaning of the same and of the fire box, and the use and operation of the device more simple, easy and satisfactory than in hitherto sug gested forms.

Certain objects and advantages of specific features as well as the advantageous results of their unitary arrangement will appear as the description of the device proceeds.

In the accompanying drawings, which form a part of this specification I have illus trated a preferred embodiment of these improvements in their adaptation for and installation in'an ordinary cooking stove or range for household or other similar use.

In these drawings Figure 1 is a sectional top plan through the fire box and contiguous end wall of such stove or range with these improvements in operative position therein, the combustion device being shown in full top plan with the exception of one of the generating tubes, which is broken away for purposes of illustration; and Fig. 2 is primarily a vertical sectional view of the same apparatus and parts, as on the line 2-2 of Fig. 1, certain portions of the device being broken away for clearness of illustration.

It is not new to install a gas generating and burning device in the fire boxes of ranges, stoves and the like, nor such as operate on the same principle as the one herein illustrated, namely, the supplying of liquid Specification of Letters Patent.

to the apparatus is maintained, such flame of combustion being utilized also for cock ing purposes.

In my present improvements the base 10, suitably a casting and carrying the gas generatlng pipe or pipes, is preferably provided with depending flanges 11, preferably at the end portions thereof, apertured to receive the bolts 12, and preferably provided with wing nuts 13 by means of which the legs or supports 14 may be clamped securely thereon. The legs 14 are provided with normally substantially vertical slots 15, through which the bolts 12 respectively pass, whereby the base 10 may be adjusted vertically as desired. A clearance 16 (Fig. 1) is provided, in the supports 14 so that the base 10 may be lowered without interference of the goose-neck generating pipe 52 and the legs 14. The foot portions of the supports 14 rest upon the grate 17, and thus the combustion device is maintained adjustably in the fire box at any desired height.

In order to maintain the base 10 and its connected parts rigidly against lateral movement in the fire box I provide a pair of adjustable stays 18 and 19, each preferably slotted as at 20, overlapping each other to some extent, and each clamped tightly upon the other and upon the base 10 by means of the bolt 21 and the wing nut 22. The stays 18 and 19 may be extended until they contact the side walls 23 and 24 re- 7 spectively of the fire box and secured rigidly in such relative position by the bolt 21. Such, or equivalent means for supporting adjustably the base 10 and its connected parts provide for the quick, easy, accurate and rigid application of the combustion device to fire boxes of various dimensions, as well as for the ready removal of the same at any time desired.

The front wall 30 of such stoves or ranges is invariably provided with a series of draft openings, as 31, and a sliding plate 32 having openings 81 adapted to register with the openings 31 wholly or in part as a greater or less amount of air is desired for combustion purposes. Frequently these draft openings and sliding draft regulator are in and upon a hinged door, as 33. As shown in the drawings, this feature of stove construction occurs at the end of the stove or range, or parallel with the longitudinal direction of the fire box. I overcome the numerous disadvantages of carrying the supply pipes through the fire box door hereinabove mentioned by utilizing one or more of the openings31, 31 for this-purpose. In Fig. 1 of the drawings the pipe 3% will be understood to leadto avsource of fuel supply, such as a kerosene tank on a sufficient elevation that the liquid willflow by gravitation through, the combustion device.

V VThis casing 35 carries the valves 36 controlled by the hand wheels 37*, and which valves may be considered to be of any approved kind, preferably of the needle valve type. Pipes 37 issue from the valves respectively, these pipes 37 being preferably copper tubes susceptible of being readily "bentiby hand as desired. The pipes 37 are alsoconnected to the elbows 38 respectively,

I preferably by a coupling whereby they may be readily removed. As will be noted from the drawings the elbows 38 are connected to the base 10, as by threading thereinto. To

maintain the operating valves and connected parts rigidly as desired I provide the stay 2 ably a wing nut 43 threaded on the end of or support39 having a fixed collar 40, a washer 41, a second washer 42 and preferthe support or bracket 39. As will be noted 7 from the drawings this holding device 39 may thus be clamped tightly upon the stove parts, as 32, 33, about one of the openings 3'1, 31. The outer end of this bracket 39is preferably flattened, as at M, and'bent so as substantially to surround the valve casing 35, a bolt and nut 45 clamping the flattened part l4: tightly'upon the member 35. These regulating valves are thus maintained in an out-of the-way yet easily accessible position,

and by means which are easy ofapplication. 1 In my usual practice the elbow 38 extends through the base 10 and one member of the coupling is threaded directly upon the projecting end thereof. The other member of the coupling is threaded upon the upright neck member 52.

tube or, pipe 51, preferably an elbow as shown, which 1n turn carries, by threading 'thereinto the generating pipe or goose- Still another feature of improvement is in "the provision of a removable closure 55,

preferably a cap as illustrated threaded.- upon the endof' the generating pipe 52, this closure being preferably nut-like in its nature, so that it may be engaged by a wrench, and provided with'an opening, as 56, communicating with the interior of the fuel pipe 52. Through this opening 56 a quantity of liquid fuel first issues until gas is generated and afterward through it the gas issues for generating and heating 'purposes. Various advantages result from this provision of a combined closure and burner, as 55, among which is that of substitution from time to time of such thereof as have openings larger or smaller as may be desired for a particular purpose. The opening 56 on one of the two caps illustrated is shown as smaller than the opening 56. Another advantage is that such cap or closure 55 may be turned on its axis from time to time, conveniently with a wrench,.as when it may be desired to have a strong and substantially undiffused flame directed'upon the cooking utensils, such flame,

of course, not being directed entirely away from the generating pipe 52 as some of its heat is necessary for the continued operation of the device. Preferably a plurality of metallic rods 63 are positioned in the upper part of the pipe 52 as well as in the upright member 51 in order to provide a greater heating surface for the liquid. fuel as well as at the same time to diminish the body of the liquid being heated at these places, thus facilitating the volatilization of the oil. This feature of the rods 63 is well known in the art.

The operation of the apparatus is as follows: Liquid fuel being admitted through one of the valves 36, the same flows through the pipe 37 connected to it, the coupling 50, elbow 51 and generating pipe 52, and a quantity thereof issues through the burner opening, as 56, and saturates the asbestos fiber-60 in the primary generating pan 61. This liquid fuel is thereupon ignited, heating the cap 55 and generating gas therein,

which gas thereupon issues through the opening 56. This gas is then ignited, and, as it is directed upward, it strikes the generating pipe 52, the liquid fuel therein being thereby heated to volatilization and thus forming new gas to issue at the opening 56. The gas flame thus continues to generate new gas and at the same time furnishes the desired heat for cooking. The flame spreader 62 is loosely positioned on the pipe 52 and may be moved. about thereon as desired.

While I have illustrated and described a preferred embodiment of these improvements, changes may be made in construction and arrangement of details thereof without departing from the spirit of the invention, and I contemplate all such changes and modifications as fall within the scope of the appended claims. 7 I claim:
